hosting iscsi on smartos

  • 772

I am trying to get back into the unix game for some storage projects we have got going. We would love to use joyents smartos (based on illumos) for that.

Working with it is a real joy (setting up vms etc) but i can't get iscsi to work.

I would love to simply share a zfs device as an iscsi connection point but cant get it to work. I also cant get smb or nfs to work, but those properties at least exist and i am sure they would work.

The documentation i can find seems a little all-over-the-place with some old solaris, new solaris, illumos stuff etc. Which is understandable since it is such a new release though.

Does anybody have any pointers ?

I already tried

zfs set shareiscsi=on zones/name

which results in "unknown property". And its not listed in the zfs properties anyway.

I also tried

sbdadm create-lu /dev/zvol/rdsk/zones/

but this results in 

sbdadm: unknown error

itadm also is not available and not service containing iscsi is listed in "svcs".

Any help is greatly appreciated.

  1. Creating an ISCSI Target

    enable the storage server and iscsi target server if necessary

    svcadm enable stmf
svcadm enable -r svc:/network/iscsi/target:default

    create a volume if necessary (sparse 10T in example)

    zfs create -V 10T -s zones/iscsi

    create a logical unit

    sbdadm create-lu /dev/zvol/rdsk/zones/iscsi

    Add a view on it (GUID is output by previous command or list-lu)

    stmfadm add-view GUID

    Create a target group to connect to (Choose a GROUPNAME and use an IP from the current server)

    itadm create-tpg GROUPNAME IP

    Create a target in this group

    itadm create-target -t GROUPNAME

  2. It is working with the February 2012 version of SmartOS. The Jan version was missing drivers.

    BTW: When writing the Feb 2012 live image of SMARTOS to a usb stick it seemed to be authored incorrectly. The grub file was looking for files in a platform subfolder which did not exist. Simply create it and move the corresponding folder into it (see grub file)
